Q.6.7.3 Electric heating coil
Check that the built-in safety thermostat with an automatic reset function and the overheat thermostat with manual re-
setting are fully operational.
Caution
Turn off the electric heating coil and let the fan run for at least 4 minutes before accessing the electric
heating coil.
Q.6.8 Plug fans
Dust can accumulate on the fan impeller which can cause imbalance and vibrations. The fan impeller must therefore be
checked once a year and cleaned, if necessary. Anti-vibration mounts and flexible connections should be checked at
the same time. If the anti-vibration mounts are damaged in any way they must be replaced.
Q.6.8.1 Motor
The motors are usually fitted with factory lubricated bearings which require no further lubrication. Larger motors can be
fitted with greasing nipples and bearings which require regular lubrication. Lubricating these types of bearings must be
carried out according to the manufacturer’s instructions.
Q.6.9 Silencer
During operation dust particles can accumulate on the surface of the baffles. Silencers that are designed for dry and
wet cleaning are fitted with baffles that can be extracted from the unit casing. Large inspection doors give access to
easily extraction of the baffles. Baffles designed for dry cleaning can be vacuum cleaned. Baffles designed for wet
cleaning can be washed down using a soft brush and soapy water. The detergent used must be non-aggressive. After
washing, the baffles must be wiped dry with a cloth. Remember to clean the inside surface of the unit casing before re-
fitting the baffles.
Q.6.10 Outdoor air section
Dust and dirt can accumulate in this section. Large inspection doors give access for cleaning.
Q.6.11 Heat pump unit

Annex 11 and 12.
